冠状动脉肌桥也称冠脉肌桥或心肌桥,是一种先天性冠状动脉分布走行的发育畸形,为冠状动脉某一段或其分支的某一段走行于心外膜下的心肌层内。这种先天性冠状动脉分布走行的发育畸形可以引起猝死,在尸体解剖中也较为常见。本文对冠脉肌桥的形态学特点、临床影像学与心电图改变、猝死机制以及法医学鉴定中需要注意的问题等方面进行了阐述。 Coronary artery muscle bridge, also known as coronary artery bridge or myocardial bridge, is a congenital coronary artery distribution of developmental malformations, a segment of the coronary artery or a branch of its branches in the epicardial myocardium. This congenital coronary artery distribution of developmental deformities can cause sudden death, the autopsy is also more common. This article describes the morphological characteristics of coronary artery bridge, clinical imaging and ECG changes, the mechanism of sudden death and forensic identification of issues that need attention.
